12 gauge 304 stainless steel trim tabs are available in standard
and custom lengths. They are guaranteed against electrolysis,
remaining strong and secure. Insta-Trim's hinges prevent most
spray and can be used for transom or bottom mounting.

Insta-Trim Boat Leveler tabs are two stainless steel planes
installed on the
transom. As the hydraulic cylinders deflect the trim tabs, water
flow is redirected.
This waterflow creates upward pressure under the trim tabs,
raising the stern.
As the stern rises the bow lowers (figure 1). Because proper trim
tab surface
area is essential, larger and/ or slower boats require larger trim
tabs than smaller
faster boats.

Insta-Trim Boat Leveler Tabs employ the force of hydraulics for
smooth
trimming action. When the trim tab rocker switch is pressed,
electrical current is
sent to the hydraulic motor pump unit. This signal activates the
electic motor,
creating fluid pressure. Valves on motor pump unit open,
channeling the
required amount of fluid to the actuators. When the trim tab
rocker switch is
released, the valve close, capturing the fluid in the actuators
hydraulic cylinders.
Thus trim tabs hold their position.

Insta-Trim Boat Leveler Tabs operate in reverse of what you might
think. The
port trim tab lifts the port stern which lowers the starboard bow.
With
properly installed trim tabs, you will not be as aware of this
reverse function as the
control functionis based on the direction you wish to move the
bow.

The proper use of Insta-Trim Boat Leveler Tabs becomes very easy
after a
short time. Here are some general guidelines to get you started:

Getting and staying trimmed
Most boats "break over" (get on a plane) at a
particular speed. This speed is determined by weight distribution,
water
conditions, etc. Insta-Trim Boat Leveler Tabs enable your boat to
plane at
speeds lower than natural planing speed. As the throttle is
pushed, the stern
squats and the bow rises (figure 3). In short bursts, the trim tab
rocker switches
are pushed in the "BOW DOWN" position, moving both trim tabs. The
boat
reacts as the stern rises and the bow "breaks over", resulting in,
among other
things, increased visibility and speed (figure 4). If over
trimming occurs as the
boat gains speed, the rim tabs can be retracted by pressing "BOW
UP".
(When overtrimmed, the boat plows, reducing maneuverability).

A powerhouse with coated wirings and a thermal overload that
resists temperature and amperage build-up. 1 3/4" stack windings
and top mounting eliminated oil leakage. The motor is mounted
with stainless steel nuts and bolts, and is easily disassembled.

Brackets

Swivel type brackets allow cylinders to be mounted an
adjusted to any angle. Knockout pins act as shear pins it tab
strikes an object.

Pump

Designed and engineered exclusively by Instatrim. The
built-in bypass is factory set at 400 P.S.I. tolerance held to
.00025. Amperage doesn't exceed 16 because the unit circulates
oil, rather than stalling out or trying to pump additional
pressure

12 gauge 304 stainless steel trim tabs are available in
standard and custom lengths. They are guaranteed against
electrolysis, remaining strong and secure. Insta-Trim's hinges
prevent most spray and can be used for transom or bottom
mounting.

Hose

Designed and manufactured exclusively for Insta-Trim with
nylon-reinforced webbing and protective PVC coating. Rated at
2000 lb. burst pressure, 15' of hose is supplied for your
system. Entering the transom 6" above the water line, the hoses
are held securely with hose trim.
Stainless steel clamps hold the hose to barb fitting at the
solenoid.

How to Use Your Insta-Trim Boat Leveler Trim Tabs

The proper use of Insta-Trim Boat Leveler Tabs becomes very easy after a
short time. Here are some general guidelines to get you started:

Getting and staying trimmed

Most boats "break over" (get on a plane) at a particular
speed. This speed is determined by weight distribution, water conditions,
etc. Insta-Trim Boat Leveler Tabs enable your boat to plane at speeds
lower than natural planing speed. As the throttle is pushed, the stern
squats and the bow rises (figure 3). In short bursts, the trim tab rocker
switches are pushed in the "BOW DOWN" position, moving both trim tabs. The
boa reacts as the stern rises and the bow "breaks over", resulting in,
among other things, increased visibility and speed (figure 4). If over
trimming occurs as the boat gains speed, the rim tabs can be retracted by
pressing "BOW UP". (When overtrimmed, the boat plows, reducing
maneuverability).

While learning to use trim tabs, begin buy pressing the
trim tab rocker switch (figure 5) in half second bursts for gradual
trimming. A momentary delay occurs from the time the trim tab rocker
switch is pressed to the time the boat reacts. To avoid overtrimming,
allow enough time between bursts to permit the boat to respond to the trim
tabs. This time depends on the boat's speed.

A good way to learn your boat's optimum attitude is to
conduct a test by running lightly loaded at a fairly high speed in flat
water. During this test, observe the bow in relation to the horizon. This
situation should reveal the boat's best running attitude. Then, under
normal operating condition, use the trim tabs to reproduce the same
attitude achieved during the test. You will know the ideal attitude by the
diminished wake, reducing laboring of engine(s), and the increased
rpm's...all at the same throttle setting. When running in a chop or
heavier seas, press "BOW DOWN", positioning the bow to cut through the
waves. This action provides a drier, more comfortable ride. In a following
sea or when running an inlet, the trim tabs should be fully
retracted for maximum rudder response. When steering from a
bridge or tower, a good trimming method is to watch the bow spray or stern
wake and the roostertail. In an untrimmed condition, the spray from the
bow is far aft on the hull, the wake is high, and the roostertail is
pronounced. When trimmed, the bow spray is farther forward, the wake is
reduced, and the rooster tail is smaller and farther behind the boat. In
addition, when trimmed, the rpm's increase.

Correction of a List

Insta-Trim Boat Leveler Tabs are operated individually to
correct a listing condition. The trim adjusts the boat's attitude in the
direction the trim tab rocker switch is pressed. If the port bow is high,
press the left-hand "BOW DOWN" direction on the trim tab rocker switch and
the port bow lowers (figure 6). If the starboard bow is high, press the
right-hand "BOW DOWN" direction and the starboard bow lowers. Do not think
about what the trim tabs are doing; just concentrate on your trim tab
rocker switch. Note: The boat should be trimmed fore and aft before
correcting for a list.

Using Trim Tabs with Power Trim

Adjust the trim tabs to achieve planing attitude.

Use the power trim to position the prop path parallel to the waterflow

Tabs let you get the most out of your power trim because the trim tabs are
trimming the hull while the power trim is trimming the prop.

Correction of porpoising

Press "BOW DOWN" in half second bursts. As
the trim tabs deflect, porpoising subsides and speed should remain the same or
increase. Only a slight amount of trim tab deflection should be necessary.
(IMPORTANT: READ "SAFETY PRECAUTIONS")

Affix
hinges and tabs to backside of transom with No. 10 x 1" stainless steel
screws, as in figure No.1 and No.2. The three inch 3" dimension, as
shown in figure No.1 is approximate and may vary, BUT ALWAYS KEEP TABS
AS FAR TO THE OUTER CHINE AS POSSIBLE. Hinge may be affixed to bottom of
hull if practical.

TAB BRACKET AND
CYLINDER
Drop hex nut into recessed area on tab bracket, with lockwasher inserted
on 5/8" s/s bolt. Come through underside of tab to contact nut and
tighten with screwdriver to MAX.

TRANSOM BRACKETS
Mount hinge and tab up from bottom of boat 1/4" as in figure No.2.
Permit cylinder bracket to rest against transom, so that trailing end of
tab is straight out or 90°. This 90° angle may vary according to
transome design. Mark bracket holes, drill and affix bracket with No.
10x1" self-tapping screws.

SIZE BIT
On fiber-glass, aluminum and steel hulls No.22 for a 5/32" hole wood use
No.35 size bit for a 3/32" hole.
TRANSOME HOLE FOR HYDRAULIC HOSE: Drill 1/2" hole on 45° up angle 6"
above waterline. Do not drill hole straight in, as this will kink hose
when applying hose trim. CAUTION: Leave ample loop in hose at hydraulic
cylinder as in figure No.2.

ELECTRIC HYDRAULIC MOTOR-PUMP
Mount motor-pump in VERTICAL POSITION AT ALL TIMES. Never fill above 3/4
level. It is desirable to mount motor-pump on inside of transom as in
figure No.1, but as it is hydraulic it can be mounted in any convenient
location. KEEP MOTOR-PUMP UP FROM BOTTOM OF BILGE SO ASNOT TO COM IN
CONTACT WITH BILGE WATER OR WASHDOWN WATER.

HYDRAULIC HOSE
Kit comes with one ample hose with hydraulic cylinder on each end. After
locating mounting position of motor - pump, cut hose (they may be of
unequal lengths) run loose ends through one half inch 1/2" transom hole
onto barb type fittings protruding out from each side of motor pump
cover. Tighten hose onto barb fitting with stainless steel clamps
provided. DO NOT OVERTIGHTEN CLAMPS.

WIRING
Connect color-code wires coming out of motor-to backside of
switches-which are also color-coded.
RED OR HOT LINE: To get proper power, connect DIRECT to BATTERY OR
STARTER
GROUND: Attach black wire to boat motor, being sure you have a good,
clean, tight connection as short as possible
FUESING: Always use our 20 amp. In line in fuse which is attached to
switches.

EXTRA SWITCH SET
Color-code wires from lower switch station to fly-bridge switch.

TO BLEED
After complete installation, work tabs up and down a few times, then
while in the UP position, remove filler-plug located on front of oil
reservoir , allow trapped air to escape, insert plug. If unit should
ever need refilling use Insta-Trim Biodegradable oil or any type of
automatic transmission fluid.

FIGURE No.3
On round bottom boats, mount hinge at Point A and B as close to bottom
of boat as possible. Disregard curvature at point C, as our hydraulic
cylinder has a ram thrust of 2 3/4"which will bring tab in contact with
water.

FIGURE No.4
Mount it the same as in figure No.1 and No.2 Mount tabs on same angle as
"V" of transform.
CURVED TRANSOM: Cut mahogany shims, as in figure No.5
DOCKSIDE: When boat is at dockside, It is recomended to keep tabs
extended.
WARRANTY: Any defective parts will be replaced on a "No Charge" basis,
in a one-year period.
DEFECTIVE PARTS MUST BE RETURNED TO FACTORY PRE-PAID FOR OUR INSPECTION
BEFORE REPLACEMENT. NO LABOR CHARGES WILL BE ALLOWED.
